The Middle Atlantic League (or “Mid-Atlantic League”) was a Class C baseball league active for 24 seasons between 1925 and 1951.

Like most of minor league baseball, the Mid-Atlantic League went dark during the peak of World War II in the summers of 1943, 1944 and 1945. Unlike many other leagues, when the Mid-Atlantic League re-organized in 1946, it featured an almost entirely new lineup of cities from the group that last played in the summer of ’42. Only the Erie Sailors returned.

Over the years the league was active in Maryland, New York, Ohio, Pennsylvania and West Virginia.
